stn vs tft display made in china

This article is introduce what is TN lcd and STN display, what is difference for FSTN and FFstn lcd? what types of lcd panel available for lcd technology? how the lcd panel display working. what is difference between FSTN and FFSTN lcd display definition? what does STN stand for? let"s see the introduction as following:

LCD is including monochrome lcd and color lcd types,monochrome lcd have TN LCD, STN LCD (yellow-green mode, blue mode, gray mode, black-white mode/FSTN,FFSTN), monochrome tft lcd. color lcd including color STN LCD and color TFT lcd types, color STN LCD (CSTN lcd) is almost phase out because it is no better than TFT in contrast, Now all CSTN LCDs were replaced by tft lcd dsiplay.

TN lcd means (twisted nematic) LCD, the namatic liquid crystal elements inside the lcd glass cell,its twisted angle is 90 degree, integrated the front and rear polarizes on the lcd, the polarized angle is also in 90 degree in cross, it control the light transmission and make the tn lcd display on and off.

STN lcd is super-twisted nematic lcd display, it is a type ofmonochrome lcd display,it is also passiveliquid crystal display(LCD). compare to TN lcd, STN LCD twist angle is 240 degree, instead of 90 degree of TN LCD, so we call it STN LCD. STN lcd have yellow-green display mode, gray,black-white mode,blue display mode,available.

The STN LCD is not only difference on twist angle in 240°, in the same time, because the liquid crystal has the double-reflective characteristic, the ambient light through the polarizer, it would change to linear polarized light, the linear polarized light go through the STN LCD cell with 240° twist angle, it would turn to oval polarized light because of the double-reflective of liquid crystal characteristic （the linear polarized light turn to two group lights via240° twist angle liquid crystal, and the two group light intervened to oval polarized light）. the oval polarized lights are always with colors, that that is the reason ofyellow-green or blue color come from for the STN LCD.

With the twist angle in 240°, it bring higherdisplay contrast as the twist angle from TN 90° to STN 240°, as see the graph as below, as the increasing about the lcd contrast in twist angle, when TN lcd can support 8 commons driver (1/8 duty), such as segment lcd, because the TN liquid crystal sharpness is less than STN LCD, if the commons higher than 8, the TN lcd contrast would be decreased dramatically. while STN lcd could support 240 commons (1/240 duty) in maximum. STN not only support 16x2, 20x4 characters lcd, and could support 128x64, 320x240 graphic lcd as well, it is all because the contrast increased due to liquid crystal"s twist angle for STN lcd.

Meanwhile, as the display contrast increased for the STN LCD, it bring wider viewing angle for STN lcd than TN lcd display. STN lcd viewing angle could be reach 120 degree, while TN lcd viewing angle around 90 degree.

FSTN lcd display mode is the profession name for black-white STN mode, it is white background and black display characters. it is the nearest color to paper in monochrome lcd, even its real background is a little near to gray. FSTN LCD mode is one of STN mode, it is mean film STN, instead of the background color to yellow-green color or blue color, FSTN LCD add a optics compensating film on the front of FSTN LCD, the optics compensating film compensate the linear polarize light and color from STN LCD, the STN LCD color turn to white background after light through the optics compensator film. that is the compensating film turn the oval polarized light to the linear polarized light again,then we could get thewhite and black lcd display. it is the display mode that near to paper.FSTN lcd is widely used in many display application because of its background.

FFSTN is FSTN LCD in negative display mode, it is also a kind of white-black stn lcd mode, FFSTN lcd is negative background with white display characters, while FSTN lcd is white background with black characters, its background would be in black, and display white characters. FSTN lcd would need one layer polarized light compensation, FFSTN would need two layers polarized light compensation on the front and rear polarizers, it would need higher cost than other STN LCD, but FFSTN LCD is best lcd soluton in STN LCD. it is higher contrast than other types of lcd.

CSTN lcd means color STN LCD, its display technology is based on FFSTN mode, but it have a RGB color filter in side the lcd glass, so it can realize to color display, and because FFSTN have high contrast, so instead lcd font display to other STN LCD, CSTN LCD is better in image display than other monochrome lcd. but CSTN lcd is still type of stn lcd, it have cross-talk effect, which decreased the contrast than TFT LCD which is active display mode without cross-talk.

Because STN lcd display is 240 degree twist angle, it have better display contrast than TN display in 90 degree twist angle. the STN display could support the 1/240 duty lcd, that with 480 segment x240 common graphic lcd. and the TN lcd only support 1/8 duty with 8 commons maximum. so TN lcd is mainly used in segment lcd display or icon lcd display. STN display is mainly used in graphic lcd display. of course, if STN lcd is also can be used segment lcd display or icon lcd display, but its cost would be around double than TN lcd display.

STN LCD display require less power and are less expensive to manufacture than,STN displays typically has lower image quality and slowerresponse timecompare than TFT displays. and tft lcd display is mainly in color display, but STN LCDs have the advantage that it can be made purely reflective for viewing under direct sunlight. STN LCD is a good choice for sunlight readable display in outdoor, for it has a display effect in outdoor and less power consumption. such as transflective STN lcd or reflective STN LCD, it can be display good without backlight light on.

TFT (thin film transistor)is still one kinds of lcd, but it active matrix lcd which without cross-talk with higher contrast than STN LCD or monochrome TN LCD. because of the thin film transistor inside, it is without cross-talk problem, and easily to get the high contrast. besides IPS tft, most of tft lcd is still TN LCD display mode, that is 90 degree twist angle to the liquid crystal.

From their discovery in 1888 to their first application within displays in the 1960s, liquid crystals have become a mainstream material choice with many impactful applications in the world of electronics.

As the key component behind liquid crystal displays (LCD), these materials change light polarization to create vibrant, high-resolution images on digital screens. The growth of LCD technology has helped propel the larger display panel market enormously, with industry valuation projected to reach $178.20 billion by 2026.

A prolific variety of LCD types has been developed to best meet their exact use-cases and end-environments. Displays may be optimized for power consumption, contrast ratio, color reproduction, optimal viewing angle, temperature range, cost, and more.

Passive Matrix LCDs offer a cost advantage (both parts and tooling) and are highly customizable. The counterpart to Passive Matrix displays are Active Matrix displays.

Furthermore, the processes used for manufacturing Active-Matrix LCDs can create much finer details on the electrode structure. This allows splitting each pixel in three sub-pixels with different color. This together with the better voltage control allows full color displays.

The transistor switches used in Active Matrix Displays must not protrude significantly above the surface of the display substrates lest they might interfere with a uniform liquid crystal layer thickness. They must be implemented in thin films of suitable materials. Hence, the name Thin Film Transistors (TFT). While AM and TFT have a different meaning, they are often used interchangeably to indicate a higher performance display.

TFTs can be formed by amorphous silicon (denoted α-Si TFT), by poly-crystalline silicon (LTPS for Low Temperature Poly Silicon), or by semiconducting metal oxides (Ox-TFT or IGZO-TFT for Indium Gallium Zinc Oxide).

Currently the most common Electronics Display Technology on the market is LCD technology and among LCD technologies, TFT display technology is the most widely used across consumer applications (laptops, tablets, TVs, Mobile phones, etc.) as well as many industrial, automotive, and medical applications.

As the first commercially successful LCD technology, Passive Matrix Twisted Nematic (TN) LCDs use a 90° twist of the nematic LC fluid between two polarizers to display information. The twist of the LC fluid either blocks light from passing through the LCD cell or allows light to pass, depending on the applied voltage. The applied voltage changes the twisted nematic orientation into an orientation that does not change the polarization of tight. This is called the TN effect.

TN displays can be normally white (NW) when they use two orthogonal liner polarizers or normally black (NB) when parallel linear polarizers are used. ‘Normally’ refers to what happens when no voltage is applied.

Initially, Passive TN LCDs were used in segmented, icon, or character displays where an image element was turned “on” and “off” depending on how the fluid was driven. Improvements were made along the way to address the limited viewing angle of TN technology, which can suffer from contrast loss or even inversion at shallow angles.

It can be advantageous to twist the director of the nematic phase a bit more than 90 degrees, but less than 180 degrees. Displays like this are a subset of TN displays and are sometimes caller Hyper Twisted Nematic Displays.

The numbers of rows or icons that can be addressed in a TN display without Active Matrix addressing is very limited. This is related to how strongly the liquid crystal responds to the applied voltage. Twisting the LC nematic fluid more than 180 degrees (typically between 210 and 270 degrees) causes the display to require a much smaller voltage difference between on and off pixels. This in turn allows addressing of many more rows without an active matrix. Displays with a twist between 210 and 270 degrees are called Super Twisted Nematic displays.

The higher display resolution of STN displays comes at a price. The optical effect is no longer neutrally black and white as in a TN display. Rather these displays are naturally yellow and black or blue and white. The color can be somewhat compensated with colored polarizers, but that comes at the expense of brightness and contrast.

The color in STN displays is caused by birefringence. Adding the same birefringence in the opposite direction can compensate for the effect. Initially this was done by stacking two STN displays on top of each other. This is referred to as Double STN or DSTN, but this is of course thicker and more expensive.

The birefringence of an STN display can be approximated with a stretched transparent plastic film. Adding such a film to an STN display instead of the 2nd STN display is a lot more attractive and has almost the same performance. This is referred to as a Film Compensated STN display (FSTN, or sometimes if two films are used as FFSTN).

FSTN displays are used commonly in consumer, medical and industrial display applications that require low cost and do not need high resolution images or full color.

Another development to the TN display was to use the same concept as in FSTN displays on TN displays. However, the film cannot just be a stretched polymer. Instead, a twisted liquid crystal structure is made and polymerized into a film that is used as a compensation film for TN displays. As this method mostly improves the display characteristics at shallow viewing angles while preserving the excellent performance in straight on viewing, this technology is called Wide View Twisted Nematic (WVTN).

The above display technologies have liquid crystal molecules that are aligned nearly parallel to the display surface with more or less twisting when going from one substrate to the other. In VA (also called VAN) displays, the liquid crystal molecules are aligned vertically with respect to the display surface. Applying a voltage causes the molecules to lay flat, with or without twist.

The advantage of this arrangement is a very dark black state with very little light leakage. This allows making displays with a black mask and colored icons or symbols. These displays look like color displays with brilliant colors, however each image element or icon can only have its assigned color or black.

Due to the ability in AM displays to address one row while the other rows are isolated, the demands on the electro-optical performance of the Liquid Crystal Configuration are less stringent. In principle, all the above mentioned configurations can be used in AM displays. In practice, TN, and WVTN are frequently used as well as some versions of VA technology described below. (MVA, AIFF-MVA, PVA, ASV).

The advantage of these technologies is a much wider and more symmetrical viewing angle along with the elimination of the contrast inversion (or color shift) seen in TN TFT LCDs when viewed from various angles. IPS and FFS displays also are less sensitive to pressure, which is a big advantage in touchscreen displays.

Here, each color sub-pixel is further divided into zones (called domains) having a different direction of the molecular movement when voltage is applied. Again, the purpose is a much wider and more symmetric viewing performance and the elimination of color shifts and contrast inversion at shallow angles. MVA technology achieves that with carefully designed protrusions on the inside surfaces of the display, while PVA uses fine patterning of the electrodes on both substrates.

The integrated circuit is a patterned piece of silicon or other type of semiconducting material. A modern IC contains millions or even billions of tiny transistors. Their tiny size allows for the fabrication of smaller, faster, more efficient, and less expensive electronic circuits. The driver chips addressing electronics displays are ICs.

Often PCBAs are connected to the display with flexible printed circuits. It’s also possible to mount all necessary components on FPCs without the need of a PCBA in the display module.

Low Voltage Differential Signaling (LVDS) is an interface to the display, not a display technology itself. This technology is not specific to displays, as it’s used in many other applications as well. It’s a high-speed signal that provides some noise immunity for the display. It also allows for longer distances compared to parallel interfaces.

As display resolutions increase, data transmission rates must increase as well. At high frequencies, single-ended signaling circuits can begin to act as antennas to radiate and receive radiated noise. Low Voltage Differential Signaling (LVDS) addresses many of these shortcomings by using differential signaling at low voltages to transmit display data at high speeds.

Mobile Industry Processor Interface (MIPI®) is a high-speed Display Serial Interface (DSI) between the host processor and the display module. It has a low pin count, high bandwidth, and low Electro Magnetic Interference (EMI), and is commonly used in cameras, cell phones and tablets.

The short name of TFT:Thin Film Transistor in Chinese. What is the difference between TFT and LCD? Our laptops and desktops now use relatively advanced TFT displays, which consist of LCD pixels and are powered by thin-film transistors integrated behind the pixels. Therefore, the TFT type display screen also belongs to a class of display devices with a source matrix.

TFT type display screen is currently a better LCD color display, TFT type display has many advantages: high responsiveness, high brightness, high contrast, and so on.TFT displays are closest to CRT displays. The TFT screen also often appears on the screen of each big mobile phone, there are 65536 colors, 160,000 colors, 16 million colors three, its display effect is also very good.

TFT means that every LCD pixel on an LCD is driven by a thin-film transistor integrated behind it. Thus can achieve high speed, high brightness, high contrast display screen information, TFT-LCD(thin-film transistor liquid crystal display) is one of the majority of LIQUID crystal displays.

Liquid Crystal Display (LCD). The structure of the LCD is placed in the middle of the two pieces of parallel glass liquid crystal box, the substrate glass set on TFT (thin-film transistor), set the color filter substrate glass on, on the TFT signal, and the voltage change to control the rotation direction of the liquid crystal molecules, so as to achieve control of each pixel display emergent polarized light or not and to achieve. Now THAT LCD has replaced CRT as the mainstream, the price has dropped a lot and become widely available.

The TFT(Thin Film Field-effect Transistor) is a video in which every single pixel in the liquid crystal display is actuated by a Thin Film Transistor embedded in the rear. Thus can achieve high speed, high brightness, high contrast display screen information.

Color screens of mobile phones vary depending on LCD quality and research and development technology. The types of color screens include STN (CSTN), TFT(LTPS), TFD, UFB, and OLED.

Liquid Crystal Display (LCD). Generally divided into monochrome and color LCD two kinds, the current monochrome LCD has almost out of the notebook computer market, and color LCD still continues to develop. The color LCD can be divided into two types: STN and TFT. The TFT(Thin Film Transistorized)LCD, also known as the active transistorized Transistor LIQUID crystal display (LCD), is the true-color LIQUID crystal display that many people describe as the Thin Film Transistor.DSTN (Dual Scan Twisted Nematic)LCD, namely double scan LIQUID crystal display. It is a display mode of STN LCD, which is no longer on the market.

What is the difference between TFT and LCD? Read here I believe you have a general understanding and cognition of TFT and LCD, LCD refers to liquid crystal display, TFT is a kind of LCD. The former is for laptops and the latter is for desktop computers. There are several different technologies for LCD, FED, PDP, OLED, TFT-LCD, they are all LCD. Only the desktop with several fronts more, lower cost, TFT technology cost is higher, generally used for notebook, or MOTO, etc., now most of the display is TFT type display, I believe we will pay more attention to the choice and purchase of digital goods.

This type of LCD was invented at the Brown Boveri Research Center, Baden, Switzerland, in 1983.twisted nematic (TN) LCDs with a 90 degrees twisted structure of the molecules have a contrast vs. voltage characteristic unfavorable for passive-matrix addressing as there is no distinct threshold voltage. STN displays, with the molecules twisted from 180 to 270 degrees, have superior characteristics.

The main advantage of STN LCDs is their more pronounced electro-optical threshold allowing for passive-matrix addressing with many more lines and columns. For the first time, a prototype STN matrix display with 540x270 pixels was made by Brown Boveri (today ABB) in 1984, which was considered a breakthrough for the industry.

STN LCDs require less power and are less expensive to manufacture than TFT LCDs, another popular type of LCD that has largely superseded STN for mainstream laptops. STN displays typically suffer from lower image quality and slower response time than TFT displays. However, STN LCDs can be made purely reflective for viewing under direct sunlight. STN displays are used in some inexpensive mobile phones and informational screens of some digital products. In the early 1990s, they had been used in some portable computers such as Amstrad"s PPC512 and PPC640, and in Nintendo"s Game Boy.

CSTN (color super-twist nematic) is a color form for electronic display screens originally developed by Sharp Electronics. The CSTN uses red, green and blue filters to display color. The original CSTN displays developed in the early 1990s suffered from slow response times and ghosting (where text or graphic changes are blurred because the pixels cannot turn off and on fast enough). Recent advances in the technology, however, have made CSTN a viable alternative to active matrix displays. New CSTN displays offer 100ms response times (for comparison TFT displays offer 8ms or less), a 140 degree viewing angle and high-quality color rivaling TFT displays – all at about half the cost. A newer passive-matrix technology called High-Performance Addressing (HPA) offers even better response times and contrast than CSTN.

Samsung had two proprietary technologies for STN LCDs, Ultra Fine & Bright (UFB), which delivered wide viewing angle (about 120 degrees), faster response time (about 60 ms) and less power consumption, while Ultra Fine & High Speed (UFS), delivered almost same color depths as TFT LCDs, greater color purity, much faster response time (about 14 ms) and same contrast ratio as TFT LCDs.

Dual Scan STN: An enhanced STN passive matrix LCD. The screen is divided into halves, and each half is scanned simultaneously, thereby doubling the number of lines refreshed per second and providing a sharper appearance. DSTN was widely used on earlier laptops. See STN and LCD.

FSTN: Film compensated STN, Formulated STN or Filtered STN. A passive matrix LCD technology that uses a film compensating layer between the STN display and rear polarizer for added sharpness and contrast. It was used in laptops before the DSTN method became popular and many early 21st Century cellphones.

CCSTN: Color Coded Super Twist Nematic. An LCD capable of displaying a limited range of colours, used in some digital organisers and graphic calculators in the 1990s

Dr Pan: Hello, Greg. STN is the abbreviation for Super Twisted Nematic. The main difference between TN, HTN, STN and FSTN LCD is the view angle. From the definition, the maximum view angle of STN LCD is 210~255 degree. Take this STN positive LCD for example. The view angle is 12 o’clock direction and it can be seen very clearly in the full view angle: 12 o’clock direction, 3 o’clock direction, 6 o’clock direction, 9 o’clock direction and the front side.

When it is a positive and reflective display, it can display without LED backlight; when it is a positive and transmissive/ transflective display, it can’t display without LED backlight, we have two options for the background color: grey background and blue letters, yellow-green background and black/blue letters.

When it is a negative and transmissive/ transflective display, it can’t display without LED backlight, the background is blue and the color of the letters is the color of LED backlight.

By the way, no matter it is a positive or negative display, the background color is affected by the color of LED backlight on some level. That is why the color of LED backlight is usually white.

It iscommonlyknown that the LCD itself can generate noise in 3D barrier applications. This noise disturbs consumers. Many LCD makers solve this problem with an expensive technology during TFT-LCD manufacturing. Unicorn has invented and patented a special technology toeliminatesuch noise.This technology canbe carriedout during normal passive LCD manufacturing processes, thus offering a competitive cost to the customers.

Unicorn has installed an advanced and automated Japanese-made optical bonding machine, which has been used widely in world-class tablet and smart phone assembly. This liquid-type optical bonding machine can be used to perform all kinds of lamination between front cover, capacitive touch panel and displays for size up to 13″ and on non-flat surface.
